72 2wd Blazer: Project "Break Me"

Stand still? Sounds like there's plenty of work to be done!

How much lift are you running on the cam in your truck? What springs? These motors are a little noisy with the fast-ramp high lift stuff like Comp XE-R lobes, etc...

Yes plenty of work, I guess I worded that wrong

I am running a patriot 226/226 585/585 with the dual gold springs and my brother is running the same in his 6.0 and it makes some noise also. I know they are bad about valvetrain noise but I thought it could be the lifters I will just put the ones I took out in my 6.0 and will probably go with a different cam in it. I just hate that I pissed $200 down the drain but I feel better knowing the lifters are good

Maybe pushrod length? Aftermarket cams generally have a smaller base circle, so you may have a little slop if you're using stock length pushrods. Just a thought...

I had a set of 7.425's in there when I built the motor and it didn't help when I put the stockers back in. I am just going to live with it since it runs so well. I did a little burn out for khoult the other day so he can vouch for the thing smoking tires, I had to get out of it or tear down the neighbors mail box

Usually the valvetrain noise is associated with both the aggressive lobes on the cam and the much increased spring pressure from a strong spring like those patriot golds. How many miles are on the lifters? Patriot springs aren't exactly gentle on the valvetrain. Sometimes its hit or miss on pushrod length. Without a way to adjust using the stock rockers, you either need to measure proper length, or test out more than one set. If it sounds really bad to the point that you would swap the cam, then it is likely that you have an issue. It could be incorrect pushrod length (or bent), broken spring, or a collapsed lifter.

Are you running stock heads? Have they been milled any?

Looking good! Question for ya what is the notch on the top of the frame rail right behind the upper arm? Also with what a great job your dad di on the front crossmember why not build your own rear crossmember? Are they just cheap enough not to try and reinvent the wheel? Last one for now, with your rear notch how low will the rockers sit with your tire size? I am still trying to invision how much I will have to chop out of mine for as low as I want to go.

Keep them pics comming, I hope with everyone doing their blazer latley mine will start working on it self

The notch you are talking about is for clearence on the end of the a-arm, if we would have used 2x4 that would not have been a issue. Yes my old man did good work but give me credit for welding it all up Yeah I couldn't see spending the time on fabbing on when it was $180 for the crossmember but if it would have been higher I would have made my own. If I measured right with a 315/35/20 I should be about a 1-2" from laying out on the rear and the front should lay "hopefully". Maybe if it warms up I will get back to work on it since I haven't touched it a month.
Thanks, Kade

Sorry, props to for the welding it looks good as well Now put on a jacket and get you butt out their and get more work done so we can sit in our warm homes and watch

Has new lifters and that helped a lot, I have also heard that headers make the noise worse and the fact the truck has poor sound deading doesn't help either. Yes stock heads and no mill.

Headers! No doubt that is causing quite a bit of ticking noises. Headers can deliver a real nice power gain and help maximize the potential, but do have their downsides. Cast iron manifolds really do help keep the noise down. You really have to buy headers with the thickest tube possible as the cheaper thin stuff is noisy.

It is a sweet ride but the roadster thing sucks if you wanna really drive one.

Few updates:
Sit body back on a week or 2 ago and made sure the rearend was "centered" in the wheel wells.
Cut the floor pan out for trans clearence. Got the motor sitting where it needs to be. Found a t56 that I am going to pick up this week so there is no longer a auto trans in the works. I know you a like to see pics but I didn't take any this time around.

[jkade]

I did pick up the 04 gto t56 today

[Rokcrln]

With out pics how do we really know it happened! J/K
Must feel good to be making forward progress.

I guess it is progress, just one less thing I have to buy now Got to get motor mounts and headers now

[jkade]

Well not a blazer update but we found out today that we are going to be blessed with a son. I am not usually one to tear up but when I saw him on that screen it did bring a few tears to my eye. Going to be cool to have a little hotrod buddy running around

[gringoloco]

Guess you need to re-think your back seat plans for the Blazer. Congrats!

Yeah, there isn't going to be one My wife says he isn't going to be riding in it anyways, she says I am to right foot heavy Thanks on the congrats.

[Palf70Step]

Congrats on the Blazer's future owner!!

He will have to buy his own Maybe he will be into VW's and won't want it

[killer71]

congratulations...mine is 4 and he is cool to have around!

[Rokcrln]

Is this your first? I we had Taylor just over nine months ago and it has been great. You will slow down and the wife will let you drive him around someday. I took my son to the dumps on his first truck ride in Low Buck when he was only a few weeks old and for the last month he has been in it everyday. Congratulations and don't worry your wife will let you touch her again some day

Yes this is the first. The good thing about me still working on the blazer is that is is over at Granny and PawPaw's house. That will give me a good excuse to go over there and work and they can have time with the baby also Maybe me working out of my dad's shop might pay off after all She still likes to be touched right now but I am sure that will change
Thanks
